ANSWER: MSB IS 1

In the 2's complement representation, the 2's complement of a binary number is obtained by first finding the one's complement (flipping all the bits), and then adding 1 to the result. This representation is commonly used to represent signed integers in binary form.

Now, if all bits except the sign bit are the same, taking the 2's complement of the binary number will result in the negative of the original number. The sign bit (the leftmost bit) is flipped, changing the sign of the entire number.

For example, let's take the 4-bit binary number

1101

  1. The 2's complement would be obtained as follows:

Find the one's complement:

0010

Add 1 to the one's complement:

0011

except the first one changes~ the first bit is the one which determines whether or not it's a negative or a positive integer

What is the significance of 26 complement in binary arithmetic?

26 decimal is 11010 binary. Its ones complement (in 5 bits) is 00101, which is 5 decimal. In 16 bits, its ones complement is 1111111111100101 which is -27 when interpreted as a signed decimal, and 65509 as an unsigned decimal.

How can you represent a negative integer in a computer system?

There are many different ways this can be done using binary form:signed magnitude, one bit is the sign (i.e. 0=+, 1=-) and the other bits are the magnitude of the number (this is analogous to how we write negative integers on paper)ones complement, invert every bit of the magnitude of a number to get its negative formtwos complement, invert every bit of the magnitude of a number then add one to get its negative form (most computers now use this form as the arithmetic circuits to do calculations in this form are simpler and thus less expensive than for the other two.There are also corresponding ways this can be done using decimal forms (e.g. BCD, 2 of 5, excess-3)signed magnitude, one bit or digit is the sign (i.e. 0=+, 9=-) and the other digits are the magnitude of the number (this is analogous to how we write negative integers on paper)nines complement, subtract every digit of the magnitude of the number from 9 to get its negative formtens complement, subtract every digit of the magnitude of the number from 9 then add one to get its negative form


What is meant by self complementing binary codes?

a binary code is self complementary if complement of any code word is again a code .in self completing codes 9's complement of a number can be obtained by interchanging 0's and 1's.

How do you get the 1's complement of 100110101?

Invert the bits of each number in the binary sequence (change all 1s to 0s, and all 0s to 1s). So, you would have: 100110101 (original number) 011001010 (one's complement)

Explain the methods which are available to store negative numbers and how are they used. Which method is mainly used today and why?

signed magnitude, one bit indicates the sign of the number and the other bits indicate the positive magnitude of the number (this system has two representations for zero: +0 and -0)one's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude (this system has two representations for zero: +0 and -0)two's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude plus one (this system is asymmetric about zero, with one more negative value than positive)offset binary, numbers are represented as the positive sum of their actual value and an offset (this system is asymmetric about zero, typically with one more negative value than positive)Most modern systems use two's complement for fixed point numbers (because the arithmetic circuitry is simpler than the others) and a combination of signed magnitude and offset binary for floating point numbers (because this format allows the same instructions for comparing fixed point numbers to also be used to compare floating point numbers, reducing the number of different instructions and the circuitry to implement them),
